Oops, I originally ran into this when I was testing using /var/tmp instead of /tmp [1], but since we aren't going this route anymore, I don't need this for my use case. I am attempting to auto-recover when a test crashes and relaunch the remaining tests and I was seeing some tests being rerun due to the lingering tmp.arglist file. This could occur on the off chance someone's /tmp is persistent or if there wasn't a clean shutdown, maybe via an OOM kill? Perhaps it is worth including for consistency's sake. I can update the commit description if we want to keep it. Let me know your thoughts. - Leah [1] https://lore.kernel.org/fstests/20221212230646.4022294-1-leah.rumancik@xxxxxxxxx/
